The key technical principles of the "Agricultural Product Quality and Safety Risk Assessment" innovation team of the Institute of Agricultural Quality Standards and Testing Technology of the Chinese Academy of Agricultural Sciences in the rapid detection of heavy metals

Recently, the "Agricultural Product Quality and Safety Risk Assessment" innovation team of the Institute of Agricultural Quality Standards and Testing Technology of the Chinese Academy of Agricultural Sciences has made important progress in the key technical theory of rapid heavy metal detection, and for the first time proposed the enhancement of heavy metal element transmission based on electrothermal evaporation microplasma Technology reveals the morphological evolution mechanism of heavy metal atoms and their nanoparticles during the transportation process

According to Associate Researcher Mao Xuefei, heavy metal pollution in agricultural products, especially grains, vegetables, and aquatic products, has attracted much attention in recent years.

The research was supported by the National Natural Science Foundation of China and the Science and Technology Innovation Project of the Chinese Academy of Agricultural Sciences
